Stainless steel chronograph wristwatches are highly sought after by collectors, existing in far few quantities than examples in gold. It is far more common for these watches to feature tachometer or telemeter scales, and an example such as the present with a pulsometer scale was likely made at the special request of a medical professional. It is exceedingly rare to find a piece of this aesthetic and horological importance; the present lot is a perfect marriage of beauty and technology.
A similar stainless steel chronograph with pulsations dial is illustrated in Lambelet, C., & Coen, L., The World of Vacheron Constantin, p. 252.
